Journal ArticleDOI
The inertial sea wave energy converter (ISWEC) technology: Device-physics, multiphase modeling and simulations
TL;DR: In this article, the authors investigate the dynamics of the inertial sea wave energy converter (ISWEC) device using fully-resolved computational fluid dynamics (CFD) simulations and demonstrate that the scaleddown 2D model is sufficient to accurately simulate the hull's pitching motion and to predict the power generation capability of the converter.
Journal ArticleDOI
A new Green–Gauss reconstruction on unstructured meshes. Part I: Gradient reconstruction
Mandeep Deka,Shuvayan Brahmachary,Ramakrishnan Thirumalaisamy,Amaresh Dalal,Ganesh Natarajan +4 more
TL;DR: The Modified Green–Gauss reconstruction is found to be consistent even on meshes with large aspect ratio and curvature with the errors being lesser than those from linear least-squares reconstruction.
Journal ArticleDOI
Critique on “Volume penalization for inhomogeneous Neumann boundary conditions modeling scalar flux in complicated geometry”
TL;DR: In this paper, the authors provide counter-examples to demonstrate that it is possible to retain second-order accuracy using Sakurai et al.'s method, even when different flux boundary conditions are imposed on multiple interfaces that do not conform to the Cartesian grid.
Journal ArticleDOI
Towards an improved conservative approach for simulating electrohydrodynamic two-phase flows using volume-of-fluid
TL;DR: It is shown that this charge-conservative numerical framework for simulating electrohydrodynamic two-phase flows still suffers from inaccuracies, particularly at high permittivity ratios and a simple solution is proposed that involves reconstruction of electric displacement rather than the electric field.
Journal ArticleDOI
Investigations of turbulence-radiation interaction in non-Oberbeck-Boussinesq buoyancy-driven flows
TL;DR: In this article, a low-Mach number (LMN) model based on the Favre-averaged (Navier-Stokes and energy) equations with the standard k-e model is presented using unstructured finite volume method.
